Letters .Patent N 96,746, dated November 9, 1869;

IMPROVEMENT IN MECHANICAL MOVEMENTS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all 'whom it 'may concern..-

The. nature of my invention consists in lthe con-- struction andarrangement of certain devices, by which an oscillating motion isconverted into a rotary motion, and also in the manner of rotating aspindle or shaft,

, in either direction, by applying a single or double Spring.

In order to enable others skilled in the art to which my inventionappertains, to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, inwhich#- 5' f lFigure l is an end View, and Figure 2, a plan view of myinvention.

.i Figure 3 is a side view of the oscillating lever, with the springsattached.

Figure 4 is a side view of the spindle or shaft and Figure 5 is aperspective view of the connectingpiece between the oscillating leverand the spindle or shaft to which it is desired to contribute a rotarymotion.

A represents the rod or lever, which, by any inachinery or device, hasan oscillating motion.

Its inner end is slightly bevelled outward', from the centre to theupper and lower edges, as seen in tig. 3, forming a depression acrossthe centre.

This end of the lever A is also slotted, and in this slot is pivoted atlnee-cornered block, a, from the base of which project two curvedsprings, b b, one above and one below the bevcllcd end of the lever.

,lhe outer angle or corner of the block a is slightly raised upward, orpressed downward, by means of a pi n, e, which is inserted either belowor above said block, through the lever A, as seen in 2 and 3.

Illhe bevelled end of the lever A is inserted into a recess, (l, in auelliptical-shaped block or cylinder, D, and pivoted in the same, saidrecess opening into a round hole, f, through the. block, running atright angles with the lever A.

'Ihe edges of the bevelled end of the lever A project slightly withinthe hole f, when the lever is either raised or lowered, but when hchl ina certain position, the edges should be even with the sides of the holej'.

The springs b b, when the lever A is pivoted in the recess d, bear onthe outside of the cylinder, one above and the other below the same.

Through thellole f, in the cylinder D, is placed a spindle or shaft, B,which, at the point where the recess d opens int-o the hole f, is notround, but polygs ouai-shaped, as shown in iig. 4.

It will readily be seen, that when the pin c is inserted, either aboveor below the block a, the lever A, by the action of the springs?) b, onthe outside of the cylinder D, becomes rigidly fixed in said cylinder,in such ainanner that one of the edges will project from the recess d,and bear against the sides of the shaft B, and consequently, when thelever A is in motion,4 that is, has its oscillating motion, it will turnthe shaft during, for instance, its upward motion, but slip over thesalue during its downward motion, and thus cause the shaft to turnsteady in one direction.

The direction in which the shaft B turns is easily changed, by movingthe pin c to the other side of the block a, as thatat once changes theposition of the edges o f the lever within the recess a, the springs bbV at alPtimes holding the lever rigid enough to turn the shaft, butstill yielding a tritie at the tirst shock.

By these means, lthe oscillating motion is converted into rotary motion,and the direction of the rotary motion is changed by the springs holdingthe oscillating level' in the required position.

Having thus fully described my invention,

That I claim as new, and desire to secure by Letters Patent, is-

1. ,'Ihe oscillating lever A, cons'cructod as described, with bevellcdend, and a slot through the saine, suhstantially as and for the purposesherein set forth.

2. Ihc tln'ee-cornered block a, provided with springs l) b,substantially as and for the purposes herein set forth.

3. The combination of the lever A, block a., springs I) b, pin e, andcylinder l), all constructed as described, and for the purposes sotforth.

4. The combination and arrangement of the oscillating lever A, with theblocka, springs b l), and pin e, the cylinder D, and shaft B, allconstructed as dcscribed, and operating substantially in thc inanucr andfor the purposes herein set forth.

1n testimony that I claim the lin'cgoing, as my own, I atlix mysignature, in presence of two 'witnesses.
